Pacom Unison

This integration allows for automatic video retrieval in case of an alarm or event for rapid visual alarm verification. Video can be recorded and played/paused which facilitates analysis of any alarm or event that has occurred in Unison. Two way audio can also be streamed between the video device and Unison (listen-in/microphone). Operators are able to manage the cameras in order to view the desired position and angle using the PTZ (Pan/Tilt/Zoom) function and select preset positions.
